9. Black Tea
Rinsing with black tea can control oral bacteria and help reduce the risk of plaque formation, thanks to its antioxidant and antimicrobial properties. Plus, it is a rich source of fluoride.
This mineral helps prevent tooth decay as it encourages better quality tooth enamel and reduces the ability of the oral bacteria to produce acid which causes tooth decay.
A 2011 study published in The Journal of Dentistry of Tehran University of Medical Sciences suggests that fluoride-rich Iranian green tea and black tea have antibacterial (Streptococcus mutans) qualities.
- Steep a black tea bag in a cup of hot water for 5 minutes.
- Squeeze the tea bag into the water to release the maximum amount of fluoride, then remove it.
- Allow the tea to cool, then use it to rinse your mouth.
- Repeat once daily to prevent plaque buildup.
